The species is divided to at least eight clades that are genetically highly divergent but morphologically similar; it may be a species complex.
W Rainfrog or Zurucuchu robber frog, Bellavista, Ecuador The first night tour in our Ecuador trip. Rain frogs, genus Pristimantis, can be very hard to identify for a casual like me. Luckily, Bellavista has a handy plate in the restaurant area that illustrates commonly seen frogs. That made it easy to single out this species, which is distinguished by its black/yellow outlines found all over its body. Despite these markings, it's still quite variable and likely a species complex. https://www.jungledragon.com/image/126419/w_rainfrog_or_zurucuchu_robber_frog_-_pose_bellavista_ecuador.html https://www.jungledragon.com/image/126418/w_rainfrog_or_zurucuchu_robber_frog_-_portrait_bellavista_ecuador.html https://www.jungledragon.com/image/126420/w_rainfrog_or_zurucuchu_robber_frog_-_back_bellavista_ecuador.html Bellavista Cloud Forest,Ecuador,Ecuador 2021,Geotagged,Pristimantis w-nigrum,South America,Spring,World
